Patent

CA 2231507

A filter medium having high stiffness is provided. The filter is a nonwoven web of conjugate fibers which has a Frazier permeability above 200 CFM, an NaCl efficiency above 75 percent, a Gurley Stiffness above 700 mg, and a SEP value of above 80. The conjugate fibers may be polyolefin, more particularly polypropylene and polyethylene in a side-by-side configuration. The medium may be made into a filter by conventional means such as pleating. Such filters are useful in HVAC systems and transportation cabin air filtration.

Milieu filtrant à rigidité élevée. Le filtre est une bande non tissée de fibres à deux composants, lesquels présentent une perméabilité Frazier supérieure à 200 CFM, un rendement NaCl supérieur à 75 %, une rigidité Gurley supérieure à 700 mg, et une valeur SEP supérieure à 80. Les fibres à deux composants peuvent être en polyoléfine, plus particulièrement en polypropylène et en polyéthylène en une configuration côte à côte. Le milieu peut être transformé en un filtre par des moyens classiques tels que le plissage. Ces filtres sont utiles dans des systèmes de chauffage, ventilation et climatisation ainsi que dans le filtrage de l'air de cabines de transport.
